Code to Create the Snake Game

Creating a complete snake game requires a significant amount of code, but I can provide you with a basic outline in Python using the `pygame` library. You'll need to install `pygame` using `pip install pygame` before running the code. Here's a simplified version:

import pygame

import random

pygame.init()

# Set up display

width, height = 640, 480

display = pygame.display.set_mode((width, height))

pygame.display.set_caption("Snake Game")

# Colors

black = (0, 0, 0)

white = (255, 255, 255)

green = (0, 255, 0)

# Snake properties

snake_pos = [100, 50]

snake_body = [[100, 50], [90, 50], [80, 50]]

snake_dir = 'RIGHT'

change_to = snake_dir

# Food properties

food_pos = [random.randrange(1, (width//10)) * 10, random.randrange(1, (height//10)) * 10]

food_spawn = True

# Clock to control speed

clock = pygame.time.Clock()

fps = 30

# Main game loop

while True:

    for event in pygame.event.get():

        if event.type == pygame.QUIT:

            pygame.quit()

            quit()

        # Arrow keys to control direction

        keys = pygame.key.get_pressed()

        for key in keys:

            if keys[pygame.K_UP]:

                change_to = 'UP'

            if keys[pygame.K_DOWN]:

                change_to = 'DOWN'

            if keys[pygame.K_LEFT]:

                change_to = 'LEFT'

            if keys[pygame.K_RIGHT]:

                change_to = 'RIGHT'

    # Validate direction

    if change_to == 'UP' and not snake_dir == 'DOWN':

        snake_dir = 'UP'

    if change_to == 'DOWN' and not snake_dir == 'UP':

        snake_dir = 'DOWN'

    if change_to == 'LEFT' and not snake_dir == 'RIGHT':

        snake_dir = 'LEFT'

    if change_to == 'RIGHT' and not snake_dir == 'LEFT':

        snake_dir = 'RIGHT'

    # Moving the snake

    if snake_dir == 'UP':

        snake_pos[1] -= 10

    if snake_dir == 'DOWN':

        snake_pos[1] += 10

    if snake_dir == 'LEFT':

        snake_pos[0] -= 10

    if snake_dir == 'RIGHT':

        snake_pos[0] += 10

    # Snake body growing mechanism

    snake_body.insert(0, list(snake_pos))

    if snake_pos[0] == food_pos[0] and snake_pos[1] == food_pos[1]:

        food_spawn = False

    else:

        snake_body.pop()

    if not food_spawn:

        food_pos = [random.randrange(1, (width // 10)) * 10,

                    random.randrange(1, (height // 10)) * 10]

    food_spawn = True

    # Draw Snake and Food

    display.fill(black)

    for pos in snake_body:

        pygame.draw.rect(display, green, pygame.Rect(pos[0], pos[1], 10, 10))

    pygame.draw.rect(display, white, pygame.Rect(

        food_pos[0], food_pos[1], 10, 10))

    pygame.display.update()

    clock.tick(fps)

pygame.quit()

quit()

Please note that this is a basic implementation, and a complete game would require additional features, optimizations, and error handling. You can expand upon this code by adding features like collision detection, scoring, game over conditions, and more advanced graphics.
